In this Reformation Sunday service, Rev. Dr. Ken Henry explores the on-going reformation of the Presbyterian Church. In his sermon, Henry examines the influence of John Knox and how the church has changed. He illustrates this reformation with bagpipes. At one point in Scotland, bagpipe playing was banned on Sundays, and on this Sunday, parishioner, and the neighborhood, were greeted by the sounds of the bagpipe playing on the front steps of the church.
